A long-acting ester of nandrolone (19-nortestosterone), the most-studied 19-nor anabolic. Added to testosterone protocols for lean mass and joint comfort, with a progestogenic side-effect profile and a very long detection window as the cost.
Full Nandrolone Decanoate page →A veterinary anabolic steroid (1-dehydrotestosterone) with a very long undecylenate ester, marketed for horses as Equipoise. Known for slow, lean, steady gains, marked appetite stimulation and a pronounced rise in red blood cell count. It aromatises at roughly half the rate of testosterone and is not progestogenic, giving a comparatively mild oestrogenic profile.
